Variant summary
Our verdict is Likely benign. The variant received -4 ACMG points: 0P and 4B. BP4_Strong
The NM_001364905.1(LRBA):c.5084T>C(p.Val1695Ala) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000489 in 1,614,190 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Synonymous variant affecting the same amino acid position (i.e. V1695V) has been classified as Likely benign.

Combined immunodeficiency due to LRBA deficiency Uncertain:2
- -
This sequence change replaces valine, which is neutral and non-polar, with alanine, which is neutral and non-polar, at codon 1695 of the LRBA protein (p.Val1695Ala). This variant is present in population databases (rs200935054, gnomAD 0.1%). This missense change has been observed in individual(s) with common variable immunodeficiency (PMID: 30363934). ClinVar contains an entry for this variant (Variation ID: 473179). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt LRBA protein function with a negative predictive value of 80%. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
